Eclipse spotters travel to Bulgarian sea coast

While Britain fretted about the high possibility of cloud cover ruining views of Wednesday's solar eclipse, many scientists travelled to the Bulgarian Black Sea coast to get a clear view of the event. A team from the Rutherford Appleton Laboratory set up equipment there to measure rapid oscillations in the sun's corona - the fiery atmosphere which is only visible during an eclipse - which could help explain why it is so much hotter than the star itself. Experts at the Moorfields Eye Hospital were hoping for dense clouds. They have been preparing for a stream of casualties who have permanently damaged their retinas by staring at the sun.
